UNITED STATES PATENT OFFICE:

WRINGER-ROLL.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed July 1, 1914. Serial N0. 848,346.

To all whom it may concern:

Be it known that I, ROBERT J. SMITH, a citizen of theUnited States,residing at the city of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inVringer-Rolls, of which the following is a specification.

This invention relates to improvements in rolls which are moreparticularly intended for use in connection with mop wringers, but whichmaybe used in clothes wringers or analogous compressing mechanisms, andit comprehends a roll embodying certain novel features of constructionand peculiar combination of parts, such as will be hereinafter firstdescribed, and then specifically pointed out in the appended claim.

The principal object of the invention is to provide a novel form of rollof the above named general character, which will be ex tremely simpleand inexpensive in construction, strong, durable and efficient inoperation, and so made as to prevent, in its use, damage to mop clothsand fiber or fabrics, which frequently occurs by the use of wringerrolls of the construction heretofore in general use.

Other objects and advantages of the invention will be disclosed in the,subjoined description and explanation.

In the accompanying drawing, which serves to illustrate theinvention-Figure 1 is a view in side elevation of a roll embodying one.form of the invention; Fig. 2 is a view in side elevation, partly insection,

showing a modification in the construction of the roll, and illustratingaportion of the same broken away; Fig. 3 is an end view of the rollshown in Fig. 1; Fig. 4 is a cross sectional view taken on line 4.-4 ofFig. 1,

looking in the direction indicated by the arrows, and Fig. 5 is'asimilar view taken on line 5-5 of Fig. 2, looking in the directionindicated by the arrows.

Like numerals of reference refer to like parts throughout the differentviews of the drawing.

Referring now to Figs. 1, 3 and 4 of the drawing, the reference numeral10 designates the body of the roll, which is tubular in form and ispreferably made of sheet metal. This body is provided, when in sheetform, with a series of depressions or.

recesses 11, which are arranged in parallel rows with one another, andas shown, the depressions or recesses 11 of one row are spaced apart andarranged so as to break the joints" of the rows on either side thereof,or, in other words, the depressions 11 of one row are located so as tointersect a cross sectional line drawn midway between the ends of thedepressions on either side of the first named row. As before stated, thedepressions 11 are formed in the piece constituting the roll 10, whilethe same is in sheet form, and such depressions or recesses may be madeby means of a punching machine, or in any other suitable manner. Thebody 10 is also provided, while in sheet form, at each of its ends witha series of inwardly extended recesses 12 to receive projections on theheads or disks 13, which are fitted in the ends of the roll 10 after thesame has been formed into tubular shape, in which shape it is firmlymaintained by means of a lock seam '14, formed at the meeting edges ofthe sheet or body 10, as will be rea Fig. 4- of the drawing. Each of thedisks or heads 13 is provided with a series of peripheral recesses 15,which are separated by extensions or projections 16, which extensions orprojections fit in the end recesses of the roll'10, and are flush withthe outer surface of said roll. The recesses 12 in the ends of the roll10 are separated by projections 17 which fit in the recesses 15 of theheads 13, and may be clenched or extended inwardly on the outer surfacethereof as at 18 (see Figs. 1 and 3 ofthe drawing), thus firmly unitingthe heads and roll 10 together. Extended centrally through each of theheads 13 is a shaft 19, which is adapted to fit in suitable bearings ofthe wringer (not shown). Inwardly of each of Bthe extensions lftfeach ofthe heads 13 is provided with an opening 20 for the outlet of water, aswell as for the discharge of the material or solution used forgalvanizing the roll when it is desired to so treat the same.

By reference to Figs. 1 and 4, it will be clearly seen, and I desire itto be distinctly understood that the depressions 11 are simplydepressions and not holes or openings, and also that the edges of saiddepressions are slightly beveled so that no abrupt edges will bepresented to the mop cloth or article being wrung or acted on by theroll.

In Figs. 2 and 5 of the drawing, is shown a modified form of the roll,which consists of an inner tube 21 which is imperforate,

ily understood by reference to and has fitted snugly thereard11nd anouter tube 22, which is provided with a series of openings 23, ofdifferent shapes, and ar-.

ranged in parallel rows with one another.

In this modification a head 13 off similarv construction to the headsshown in Figs. 1, 3 and 4 and above described, is applied to each end ofthe inner roll 21 and is fitted to the outer roll 22in the same manneras the heads 13 are fitted to the roll 10 in the first describedconstruction. It will be understood that in the modified constructionthe inner roll or tube 21 will form bottoms for pressed by the rollersof the wringer,will be forced into the depressions, but as they aresimply depressions and not holes no damage to the cloth or fabric canoccur, yet

gnaw? the operation of wringing the same or exinvention, it is apparentthat it canbe done in a very cheap and simple manner, and that a verydurable roll will be afiorded.

Having thus fully described my invention what I claim as new and desireto "secure by Letters Patent is i A wringer-roll consi body havingtherein a series of depressions and provided at each of its ends wlthalter- L sting o l? a tubular nating recesses and extensions, and a headfitted in each end of the body and provided at its periphery withalternating extensions and recesses .to fit in and receive respectivelythe recesses and extensions of the body.
